Clients come to me when the numbers have to be right. Not approximately right. Not good enough for now. Right. That standard is why businesses rely on my models for real decisions, why researchers trust me with peer-reviewed work, and why clients across healthcare, finance, marketing analytics, environmental science, and government research keep coming back. With 4+ years delivering analysis that holds up under expert review and scales across industries, one principle drives every engagement: the method always follows the problem. ________________________________________ What I Deliver ________________________________________ 📊 Statistical analysis and modelling: regression, ANOVA, hypothesis testing, EFA/CFA, SEM, cluster analysis, survival analysis, longitudinal modelling, and Bayesian hierarchical models and meta-analysis. 🤖 Data science and machine learning: predictive modelling, classification, clustering, time series forecasting, NLP, and sentiment analysis in Python and R, from raw data through to documented, deployable output. ✨Qualitative and mixed-methods research: thematic and content analysis in NVivo, ATLAS.ti, and MAXQDA; survey design, psychometric validation, and scale reliability testing. 📈 Business intelligence and analytics: Power BI and Tableau dashboards, A/B testing, financial modelling, KPI reporting, and operational analytics across corporate, government, and research settings. 🎓 Research and academic consulting: study design, sampling strategy, methodology development, results interpretation, and formatted output across healthcare, education, environmental science, social research, and doctoral projects. ------------------------------------------------------------------------------------------------------ ⚙️Tools: R, Python, SPSS, Stata, SAS, SQL, MATLAB, EViews, Minitab, Power BI, Tableau, Excel, NVivo, ATLAS.ti, MAXQDA, REDCap, Qualtrics, KoboToolbox, ODK, LaTeX, Jupyter, Git, AWS, Google Cloud, Azure. ------------------------------------------------------------------------------------------------------ ________________________________________ Where Most Analysts Fall Short ________________________________________ Most data projects fail at interpretation, not analysis. The model runs, the output is generated, and then nobody can explain what it means or what to do with it. That is the gap I close. Every deliverable includes documented methodology, transparent assumption testing, plain-language interpretation, and results structured for the audience that will use them, whether that is a business stakeholder, a doctoral committee, or a peer reviewer. I ask the questions most analysts skip, flag problems before they become expensive, and communicate clearly at every stage of the project. My Upwork record reflects this: a 100% Job Success Score, a 5.0 rating, and returning clients. Not because the work was fast or cheap, but because it was correct. ✅ Send me your project brief. I respond within 24 hours.

I'm a data analyst and market research consultant with deep expertise in survey design, statistical analysis, and data visualization. I love digging into data and uncovering the stories beneath it--whether that means programming a complex survey, building a regression model, or turning messy datasets into clear, actionable insights. My market research work spans end-to-end study design and execution, including concept testing, conjoint analysis, and pricing studies (Gabor-Granger, Van Westendorp). I have specific industry experience in health care, pharma/biotech, SaaS, and Consumer Packaged Goods (CPG). On the survey programming side, I'm a Qualtrics expert, and highly proficient in Alchemer, SurveyMonkey, TypeForm, and other platforms (including advanced branching and skip logic, quotas, translated surveys, embedded data, custom JavaScript/HTML, API integration, and panel provider integration). For data analysis, I was trained as an academic biostatistician (M.P.H., Tufts University) and bring rigorous statistical chops to every project (regression analysis, segmentation, cluster analysis, and more). I principally use Stata, SPSS, and Excel. I visualize findings in Tableau and Power BI, and deliver polished reports in PowerPoint or Word. My background includes roles at UC San Diego (data analyst and research associate) and Harvard Medical School (health economics data analyst), giving me a strong foundation in both research methodology and real-world data challenges. Here's a snapshot of what I can help with: • Survey programming — Qualtrics, Alchemer, SurveyMonkey, and more, with advanced logic, quotas, and custom scripting • Market research — concept testing, pricing studies, conjoint analysis, segmentation • Statistical analysis — regression, clustering, mixed methods, and robust modeling • Data visualization — Tableau, Power BI, and presentation-ready reporting • Data management — cleaning, merging, and wrangling complex datasets I'm a responsive, collaborative freelancer who's genuinely passionate about data. Whatever your project, from small surveys to a full research study, feel free to send me a message or schedule a call to discuss your needs. I look forward to working with you! Donald Clermont
